November 20, 2025 To the federal safety agency Office of Defects Investigation Subject: Safety Defect Complaint â Tesla Model S I am submitting this complaint regarding a serious and dangerous safety defect involving my Tesla Model S. Safety Defect Summary:    â¢Â   After the high-voltage battery failed, the vehicle would not enter Neutral.    â¢Â   I had to use Tow Mode in the middle of a street on a hill to avoid blocking traffic.    â¢Â   Once in Tow Mode, the car could not enter Park and the emergency/parking brake would not engage.    â¢Â   The car became completely free-rolling, posing danger to myself, other drivers, and pedestrians.    â¢Â   When Tesla returned the car to my home, their technicians also could not get the vehicle into Park or activate any emergency braking system.    â¢Â   The car is currently stuck in Tow Mode in my driveway with physical objects placed behind the wheels to prevent it from rolling. Why This Is a Safety Hazard: A vehicle that cannot shift into Park, cannot use its emergency brake, and remains free-moving after a failure represents a serious safety defect. This occurred without warning and left the vehicle unsafe to operate or even store. Request: I respectfully request that the federal safety agency investigate this as a potential safety defect affecting the Tesla Model S when the high-voltage battery fails. A car should never lose all ability to secure itself.

Loss of rearview camera
On November 20, 2020, the Office of Defects Investigation (ODI) opened Engineering Analysis (EA) 20-003 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-18 Tesla Model S and model year (MY) 2016-2018 Tesla Model X vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device. During its investigation, ODI learned that the expected usage life rating for the 8GB eMMC NAND flash memory device is approximately 3,000 “P/E” or Program-Erase cycles, after which the eMMC NAND flash memory device would become fully consumed and no longer be operational, leading to a failure of the media control unit (MCU). At a daily cycle usage rate of 1.4 per block, accumulation of 3,000 P/E cycles would take only 5-6 years. Historically, the expected life of a vehicle generally far exceeds 5-6 years of service. ODI believes that a 5- or 6-year life expectancy for a component integral to providing the driver with safety functions is insufficient. During our review of the data, Tesla provided confirmation that all units will inevitably fail given the memory device’s finite storage capacity. Tesla provided its own statistical model showing the number of projected weekly MCU repairs from 2020 to 2028, estimating that replacement rates for MCU failures will peak in early 2022 and gradually decline until (near) full part turnover has been accomplished in 2028. According to Tesla, for subject vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device, the eMMC NAND cell hardware will fail when reaching lifetime wear, for which the eMMC controller has no available memory blocks necessary to recover. With this failure mode, the only recovery available is a replacement of the eMMC device, achieved by physical part replacement of either the MCU assembly or visual control module subcomponent. Tesla provided information concerning the effects of MCU failure on vehicle function, which include in loss of rearview/backup camera and loss of HVAC (defogging and defrosting) setting controls (if the HVAC status was OFF status prior to failure). The failure also affects the Autopilot advanced driver assistance system (ADAS) and turn signal functionality due to the possible loss of audible chimes, driver sensing, and alerts associated with these vehicle functions. Based on this analysis, ODI issued a Recall Request Letter (RRL) on January 13, 2021. The RRL was based on ODI’s tentative conclusion that a defect related to motor vehicle safety exists in the subject vehicles because the eMMC NAND flash devices have a finite lifespan based upon the number of program/erase (P/E) cycles, after which the MCU fails due to memory wear-out, which constitutes a premature failure of safety-critical part. Tesla responded to the Recall Request Letter (RRL) on January 27, 2021, and disputed the tentative findings of the RRL. Nevertheless, on January 29, 2021, Tesla filed a safety recall (21V‑035), recalling (MY) 2012-2018 Tesla Model S and (MY) 2016-2018 Model X vehicles with a center display equipped with a NVIDIA Tegra 3 processor and an 8GB eMMC NAND flash memory device. In this recall, Tesla is providing a free hardware remedy in addition to the over-the-air (“OTA”) firmware updates that the company had previously implemented. the federal safety agency will continue to monitor the issue as part of its ordinary processes for overseeing the effectiveness of recalls. However, based on available information, at this time, Tesla’s recall appears to address the unreasonable risk to motor safety presented by the premature failure of the component. Accordingly, the investigation is closed. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to

Loss of rearview camera
On June 22, 2020, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE20-010 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-2015 Tesla Model S vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device. EMMC NAND flash devices have a finite lifespan based upon the number of program/erase (P/E) cycles. The subject MCU allegedly fails prematurely due to memory wear-out of the eMMC NAND flash. Tesla used the same MCU with the Tegra 3 processor in approximately 159 thousand 2012-2018 Model S and 2016-2018 Model X vehicles built by Tesla through early-2018. In response to ODI's Information Request (IR) for PE20-010, Tesla provided ODI with 2,399 complaints and field reports, 7,777 warranty claims, and 4,746 non-warranty claims related to MCU replacements. The data show failure rates over 30 percent in certain build months and accelerating failure trends after 3 to 4 years-in-service.According to Tesla, for subject vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device, the eMMC NAND cell hardware can fail when reaching lifetime wear, for which the eMMC controller has no available blocks to recover. With this failure mode, the only recovery available is a replacement of the eMMC device, achieved by physical part replacement of either the MCU assembly or visual control module subcomponent. Tesla provided the effects of MCU failure on vehicle function which result in loss of rearview/backup camera, loss of HVAC (defogging) setting controls (if the HVAC status was OFF status prior to failure.) There is also an impact on the advanced driver assistance support (ADAS) Autopilot system, and turn signal functionality due to the possible loss of audible chimes, driver sensing, and alerts associated with these vehicle functions. There are precedents for addressing defects that result in loss of either backup camera, defogging, or turn signal functions under safety recalls.Tesla has implemented certain Over-The-Air or OTA updates to subject vehicles to mitigate the effects of MCU failure. These updates include firmware changes to reduce memory usage of the subject memory card, improve eMMC error correction and storage management strategies, changing the control logic for turn signal activation, and defaulting the HVAC system to Auto (71.6F) for drives after MCU failure to address windshield defogging. Tesla indicated that the MCU failures are likely to continue to occur in subject vehicles as vehicles continue to operate and use available memory in the 8GB eMMC NAND flash memory until 100% of units have failed. This investigation has been upgraded to an Engineering Analysis (EA20-003). The VOQs associated with the upgrade of this investigation are identified in the attachment to this resume.

The contact owns a 2013 Tesla Model S. The contact stated that while driving at an undisclosed speed, the center display screen malfunctioned, causing the rearview camera to intermittently fail. Additionally, the failure caused a delay while switching gears to drive(D) and to park(P). The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and determined through the Tesla App that the VCM daughterboard needed to be replaced with one containing an enhanced eMMC controller. The contact related the failure to the federal safety agency Campaign Number: 21V035000 (Back Over Prevention, Visibility, Exterior Lighting) however, the VIN was not included in the recall. The failure mileage was approximately 95,500.
Sept 30, 2022. Driving East bound on interstate 10 ,east of Tallahassee FL, car started flashing dash RED. Car applied brakes while going 70 mph. Car made me pull off the road because of applied braking. It would not release the brakes. I called Tesla Roadside assistance, "you have a flat tire". Attached are screenshots. I didn't have a flat tire. Had to get towed 300 miles home. Next day brakes released, drove car. I keep getting error codes everyday. Car has been in service, "nothing wrong". This a safety Hazzard, imagine in heavy traffic on a bridge.

The contact had taken the vehicle to a dealer, where it was diagnosed and determined that the eMMC controller needed to be replaced. The vehicle was repaired; however, the failure occurred again and the eMMC controller was replaced a second time. The failure persisted. The failure mileage was 123,864.
The car suddenly has a powertrain issue, but it is a widely known problem with some estimates of 66% of all early Teslas having a powertrain issue by 60k miles. Mine happened at 56k. There is clearly a defect with early Tesla powertrains, as they increased the warranty to 8 years or 50k miles. My car is now at 9 years, and because of the low mileage due to covid, they will not cover the powertrain issue of the car. The following are links proving significant issues of my car. https://www.greencarreports.com/news/1093907_tesla-model-s-drivetrain-warranty-rises-to-8-years-same-as-battery-pack https://www.vehiclehistory.com/articles/tesla-problems-3-major-issues-you-need-to-know-about https://www.autoevolution.com/news/early-tesla-model-s-powertrain-reliability-issues-come-into-question-in-low-volume-study-102773.html I not only have the powertrain issue, but my center screen is also screwed up. This is a massive issue in Teslas because I cannot access my HVAC controls, or any safety controls with this not working. I have contacted Tesla numerous times, I will be happy to provide email exchanges and they have not done anything to help me except want to charge me a lot of money, 9k to fix all of this!
Part ii after I emailed tesla kearney mesa service station, with my concern about their billing for the recall and customer service; I was sent a new billing. Mind you, all my issues are related to the recall and tesla schemes and falsehoods. See attached
The contact owns a 2013 Tesla Model S. The contact received notification of the federal safety agency Campaign Number: 21V035000 (Back Over Prevention, Visibility, Exterior Lighting) however, the part to do the recall repair was not yet available. The local dealer was contacted and it was confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure. Parts distribution disconnect.
The vehicle's main center console doesn't work, even after a recall notice from Tesla. Tesla tried to see what was going on with my car, but they could not find it, but 5-10% of the time my car still has a center console screen not working. There is a defect and these times it is very dangerous to drive the car.
Hi, Tesla has a recall from the federal safety agency regarding the MCU chip that powers the main center console screen. It can fail over time. My vehicle is under the recall, and they did the MCU chip recall but it did not help the screen. It is still failing. Without the screen working, the vehicle controls are not usable since 95% of the functions are through the screen. I contacted Tesla and they have ignored me and declined to fix the vehicle, even though the purpose of the recall was to fix the center screen.
